For Yellowstone’s central star, it would mean that he can spend more time with his family, which he hasn’t been able to do as much while shooting Season 4.
But on the other hand, it would also mean that viewers would have to keep up with the show’s ensemble separately.
If these scenarios were to play out, it would be a potential avenue to have less Kevin Costner/John Dutton-centric activity per season.
Such a move would actually help Costner, who has been open about his struggles adjusting to television.
